自锚式悬索桥的静力性能模型实验研究

自锚式悬索桥作为一种特殊的桥型，在设计理论和施工监控方面，均与传统的地锚式吊桥有很大的差别。鉴于理论研究方面的滞后性，对一座主跨为160m的混凝土自锚式悬索桥进行了模型实验研究，获得了反映该座桥梁结构力学性能的主要指标，初步掌握了该类桥型的工作状态，并且通过与理论结果的对比分析证明了有限位移理论是适用的。模型实验所得的结论对该桥的设计和施工监控具有指导作用。同时，为该类桥型的计算理论提供了实验依据。

Research on the Static Model Test of Self-anchored Suspension Bridge

Self-anchored suspension bridge, as a special type of bridge, is much different from traditional earth-anchored suspension bridge in design and construction control. Due to the posteriority of theoretical research, model test for a concrete self-anchored suspension bridge with 160 meters main span is performed in this paper, and some mechanics properties indexes are obtained. The characteristics of this new type bridge under loads are known basically through the model test and finite displacement theory proved to be suitable by the comparison between test results and calculated ones. Conclusions obtained here can provide theoretical guidance for engineering design and construction control of the bridge as well as be used as important references for calculating theory of this type bridge.
